electrical connector

Abstract

The invention discloses an electrical connector, which comprises an insulating body, which is provided with a plurality of receiving holes; a plurality of terminals, each terminal is located in each receiving hole, and the terminals are provided with a holding part; a plurality of solder columns, each A solder column is provided with a base, a fixing portion extends upward from the base, a welding portion extends downward from the base, the base has a first surface, the welding portion has a second surface, the first surface and the second surface meet and form An intersection angle, the width of the base is greater than the maximum width of the fixed part, and the width of the base is greater than the maximum width of the welded part, the fixed part is held by the holding part, and the welded part is located outside the holding part. On the other hand, when the solder column is assembled into the receiving hole, the contact between the fixture and the welded part is planar contact. The contact area between the fixture and the welded part is large and stable. The fixture can clamp the solder column stably, reducing the difficulty of assembly and improving the assembly efficiency.

Description

technical field The invention relates to an electrical connector, especially an electrical connector electrically connecting a chip module to a circuit board. Background technique The existing electrical connector includes an insulating body, a plurality of terminals and a plurality of solder posts, the terminals have holding parts, the solder posts have a base and a fixing part extending upward from the base, the base is a hemisphere shape, the fixing part is cylindrical and the holding part stably holds the fixing part. During the assembly process, the base part is usually clamped by a jig and assembled into the holding part from bottom to top, because the The base is hemispherical. When the base is clamped by the clamp and assembled into the holding part, the clamp contacts the outer surface of the base. Since the outer surface of the base is arc-shaped, the clamp clamps the base The contact force of the outer surface is not uniform, so the relative displacement between ...

The existing electrical connector includes an insulating body, a plurality of terminals and a plurality of solder posts, the terminals have holding parts, the solder posts have a base and a fixing part extending upward from the base, the base is a hemisphere shape, the fixing part is cylindrical and the holding part stably holds the fixing part. During the assembly process, the base part is usually clamped by a jig and assembled into the holding part from bottom to top, because the The base is hemispherical. When the base is clamped by the clamp and assembled into the holding part, the clamp contacts the outer surface of the base. Since the outer surface of the base is arc-shaped, the clamp clamps the base The contact force of the outer surface is not uniform, so the relative displacement between the fixture and the outer surface of the base is easy to occur, that is, the base is easy to slide in the fixture, and the solder column is easy to slip from between the fixture during the assembly process.
